- the Rie tool is clamped by the joe.
- the clutch mechanism rotates from the rotating nut. Power transmission to the members is intermittently shut off.
- the tool clamping force can be increased by the clutch mechanism by the impact force due to the intermittent power transmission blocking action as described above, and the tool Can be released smoothly.
- FIG. 1 is an overall side view showing a first embodiment of the present invention.
- FIG. 2 is a front view of the whole clutch mechanism taken along line AA in FIG.
- FIG. 3 is a front view of a rotating nut of the clutch mechanism taken along line B—B in FIG.
- FIG. 4 is a partially enlarged plan sectional view of the clutch mechanism.
- FIG. 5 is an enlarged side sectional view of the upper half showing an operating state.
- FIG. 6 is an overall side sectional view showing a second embodiment of the present invention.
- FIG. 7 is a front view cut along a line AA of FIG. 6.
- FIG. 8 is an overall side sectional view showing a third embodiment of the present invention.
- FIG. 9 is an overall side sectional view showing a fourth embodiment of the present invention.
- FIG. 10 is an overall side sectional view showing a conventional example.
- FIG. 11 is a partially cutaway front view of FIG.
- FIGS. 1 to 9 Embodiments of the present invention shown in FIGS. 1 to 9 will be described below.
- reference numeral 1 denotes a chuck main body, and three jaws 2 are radially provided on the chuck main body 1 so as to be slidable for expansion and contraction.
- the pivoting member 3 is rotatably provided on the chuck body 1 and the pivoting nut 4 divided by the dividing groove 4a for assembly after assembly on the chuck body 1 is rotatable. To maintain the shape of the rotating nut 4.
- Form 8 is press-fitted onto the outer peripheral surface of the rotating nut 4, and the female screw 9 of the rotating nut 4 is screwed into the male screw 10 on the outer peripheral surface of the jaw 2, and the outer peripheral surface of the rotating member 3
- the seat plate 13 is located on the rotating nut 4 side of the flange portion 12 of the chuck body 1, and a plurality of concave portions 11 are provided between the seat plate 13 and the rotating nut 4.
- a spherical bearing body 14 is interposed.
- Reference numeral 15 denotes a gripper, which is fixed to the chuck body 1 to prevent rotation and has a concave portion 16 formed on the outer peripheral surface.
- Reference numeral 17 denotes a clutch mechanism.
- two concave portions 4b and two convex portions 4c are formed in the rotating nut 4 at 90-degree intervals, and an annular body 1 integrated with the rotating member 3 is formed.
- 8 are formed with two recesses 18a in the range of 150 degrees and two ⁇ portions 18b in the range of 30 degrees.
- a clamp panel 20 for pressing the rotating member 3 rightward in the drawing is provided between the ring 8 and the locking ring 19.
- the first embodiment has the above-described configuration, when the rotating member 3 is rotated by grasping the grip 15, the engagement between the convex portion 4 c and the convex portion 18 b of the clutch mechanism 17 is established.
- the rotating nut 4 is further rotated, and the jaw 2 is caused to slide forward and backward by the screwing action between the rotating nut 4 and the jaw 2, and the jaw 2 is used to clamp the Rie tool W. Can be done.
- the rotating member 3 can idle, so that injury to the palm of the operator can be prevented, and safety can be improved.
- the clamp machine 17 makes it easier to stabilize the rivet clamp.
- three jaws 2 are radially provided on the chuck body 1 so as to be slidable for expansion and contraction, and the rotating member 3 is attached to the chuck body 1. It is rotatably provided, and a rotatable nut 4 is provided rotatably on the chuck body 1 through a dividing groove 4a for assembling after manufacture, so that the rotatable nut 4 is retained.
- Form ring 8 is press-fitted onto the outer peripheral surface of rotating nut 4 to form concave ring grooves 1a and 8a on the inner peripheral surface of shape retainer 8 and the outer peripheral surface of chuck body 1, respectively.
- one ball insertion hole 21 is formed in the shape retainer 8, and a plurality of spherical bearing bodies 14 are arranged between the concave grooves 1 a and 8 a via the ball insertion hole 21.
- the plug 22 is press-fitted into the insertion hole 21, and the retaining ring 8 and the rotating nut 4 are supported by the bearing 14 in the axial direction and the rotating direction with respect to the chuck body 1. ing.
- the clutch mechanism 17 forms four convex portions 18b and another concave portion 1 ⁇ a on the body 18 pressed into the rotating member 3, Four convex portions 4c and another concave portion 4b are formed on the rotating nut 4, a locking portion 19 is formed on the inner peripheral surface of the rear portion of the rotating member 3, and the shape retaining ring 8 and the locking portion 19 are formed.
- a clutch spring 20 that presses the rotating member 3 to the right in the figure is provided between them.
- the second embodiment has the above-described configuration, similarly to the first embodiment, the impact force due to the intermittent contact between the protrusion 18b and the protrusion 4c is used as a reaction force to the rotating nut 4. As a result, it is possible to increase the pressure of the Rier device and to release the tool W smoothly.
- the ring 18 of the second embodiment shown in FIGS. 6 and 7 is formed integrally with the rotating member 3, and the cover 23 is pressed into the chuck body 1.
- the locking ring 19 is fixed to the rotating member 3 instead of the locking portion 19, and the other structures are configured in the same manner.
- the third embodiment differs from the second embodiment in terms of assembly, but provides the same operation and effect.
- the cover 23 is press-fitted and fixed to the chuck body 1 and the ring 18 is removed to directly form the convex portion 18 b and the concave portion 18 a on the rotating member 3, and the convex portion 18 b and the concave portion
- the clutch mechanism 17 is constituted by 18 b, the convex portion 4 c and the concave portion 4 b of the rotating nut 4, and other structures are similarly configured. Even in the fourth embodiment, the same operation and effect as those of the first, second, and third embodiments can be obtained.
